Remove LINUX_VERSION_CODE > 4.4.0 check to support older kernels that use the newer nvme_ioctl.h

Subject: [PATCH] Use nvme_ioctl.h for newer kernel versions #55
The header linux/nvme.h was replaced by linux/nvme_ioctl.h in kernel versions greater than 4.4: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9d99a8dda154
The needed structs and opcodes are copied into a new header file from nvme.h.
